As an application in the field of environmental protection, environmental risk management includes the following behaviors: selecting the effective control technology to analyze the expenses and benefits of the risk cut-down, according to the result of the environmental risk appraisal, the appropriate rules and regulations; confirming the acceptable risk level and acceptable harm level; carrying on policy analysis considering society economic and political factors; determining proper control measures and putting into effect, in order to reduce the accident risk degree, and then protect the human health and the ecosystem security.

作为风险管理在环境保护领域的应用，环境风险管理是指根据环境风险评价的结果，按照恰当的法规条例，选用有效的控制技术，进行削减风险的费用和效益分析；确定可接受风险度和可接受的损害水平；并进行政策分析及考虑社会经济和政治因素；决定适当的管理措施并付诸实施，以降低或消除事故风险度，保护人群健康与生态系统的安全。

General terms of the standard cylinder , piston bore width of about 20% to 25% of the value of comprehensive need to consider the use of conditions, from the piston and cylinder, piston rod and the guide sleeve of the gap size and other factors to decide.

一般对标准气缸而言，活塞宽度约为缸径的20%～25%该值需综合考虑使用条件，由活塞与缸筒、活塞杆与导向套的间隙尺寸等因素来决定。

Whether current field , temperature field and flow field are designed reasonably or not are critical for the design of rare earth electrolysis cell, therefore, the study on current field and temperature field is very important.

怎么样设计合理的电场、热场、流场是决定电解槽设计好坏的关键因素，所以，有关电场、热场、流场的研究显得十分重要。

Feng shui masters, traditional lunar almanacs, lucky numbers like "8" and Chinese holidays like the mid-autumn festival have long helped Chinese people decide when to tie the knot.

风水大师、传统黄历、8这样的幸运数字、中秋节之类的传统节日；这些因素长期以来都帮助着中国人决定他们的婚姻大事。

The purpose of this work is to develop new methods for syntheses of polyimides derived from chlorophthalic anhydrides.

本工作的目的是以氯代苯酐和二胺为原料，制备双氯代酞酰亚胺单体，然后进行聚酰亚胺合成方法的研究，以达到减少合成步骤，降低其生产成本的目的，主要内容如下： 1由双氯代酞酰亚胺与双酚A在不同体系中进行聚合反应，发现双酚是否完全成盐和聚合体系含水量是决定聚合物分子量的关键因素。

To begin with the review of human's understanding on the brain, we will explain the brain formation and working principles in simple terms. How the complex and ingenious structure of brain is formed? Why can we see the colorful world? Why can we hear the sweet warble of the bird and touching music? Why do we have intelligence and thoughts? Why do we have pleasure, anger, sorrow and joy? How can we acquire information and form consolidated memory, and what can affect the learning and memory? Why do we need sleep, and what determine the biorhythm? How do we control our movement, thinking and emotion? How do Alzheimer's disease, stroke, depression, anxiety, schizophrenia, and drug addiction happen? Can adult neuron regenerate?

从回顾人类对脑的认识过程开始，我们将一步步深入浅出的告诉你大脑形成和工作的原理：大脑复杂而精妙的结构是如何形成的；我们为什么能看到色彩缤纷、千姿百态的世界；为什么能听到悦耳动听的鸟的啼啭和动人心弦的音乐旋律；我们为什么有智力、能思维；为什么有喜怒哀乐；我们如何获取信息并形成牢固的记忆，哪些因素影响学习记忆的过程；我们为什么需要睡眠，是什么决定了我们的生物节律；我们如何控制自己的运动、思维和情绪；老年痴呆、中风、抑郁、焦虑、精神分裂症、药物成瘾是如何产生的；成年脑神经细胞能再生吗？

When the molecule C 60 Buckminsterfullerene and its elongated cousins the carbon nanotubes or Buckytubes were discovered, it suddenly became clear that our understanding of the factors governing the bottom-up assembly of atomic and molecular structures involving carbon and other atoms was quite na ve – especially with regard to dynamic construction events at nanometer dimensions.

当发现C60分子及其延伸物碳纳米管或巴基管时，人们突然清楚地了解到有许多因素决定碳原子结构，并且其它材料也是如此，尤其是关于在纳米级尺寸下的情况。
